Our Verdict
LG 27GR95UM-B
LG 27G850A-B
The LG 27GR95UM-B and the LG 27G850A-B are both 4k gaming monitors, with a few differences. The 27G850A-B has the advantage if you want something for PC gaming at high frame rates, as it has a higher native refresh rate than the 27GR95UM-B, and it has a Dual-Mode feature that switches it to a 1080p resolution and 480Hz refresh rate. The 27G850A-B also has DisplayPort 2.1 bandwidth to take advantage of modern graphics cards. On the other hand, the 27GR95UM-B is the better choice if you care about good picture quality, as it's a Mini LED monitor with deeper blacks and brighter highlights. However, it's not a perfect solution as its local dimming feature causes haloing around bright objects.
